Shielding efficiency is a result of material composition, specific gravity, thickness, grain structure within the alloy, and hardness. Selection and use of one or more of our exclusive formulated alloys, MuMETAL®, Co-NETIC®, or NETIC® is determined by power source, strength of the unwanted field (HO ), and the field attenuation required for your application.
- MuMETAL® Stress Annealed Sheet – maximum permeability, low intensity fields, fabrication
- Co-NETIC® AA Perfection Annealed Sheet – maximum attenuation, flat shields, doors, walls
- NETIC® Sheet & Foil – strong fields, high magnetic saturation, fabricated or flat shields
MuMETAL® Alloy – Known as the Industry Standard
Available as Stress Annealed Sheet or partially annealed for ease of machinability. Sheet stock is used for fabricated shields such as enclosures, cylinders, cans, channels or 3D boxes. Typically, atmospherically controlled annealing is required after stamping, machining, bending, rolling or welding to provide maximum shielding performance. MuMETAL® is available in many forms, but most shields are fabricated from our MuMETAL® Sheet and Foil. Our stock MuMETAL® Foil is Perfection Annealed and does not require re-annealing unless severe forming or heliarc welding is performed. Learn More: Fabrication Capabilities
